This invention pertains to hinges of a type substantially similar tothat constituting the subject matter of my pending applicationSerialNumber 105,762, filed Oct. 15, 1936, on which the present deviceconstitutes an improvement.

An important object of the present invention is to provide, in aconcealed hinge particularly for automobile doors and including apivotally mounted supporting member on which the door is slidablymounted, together with a toggle for actuating the door on saidsupporting member, new and novel means for connecting said toggle tosaid supporting member for actuation thereby.

Another important object of the invention is to provide a novelconstruction and arrangement of supporting member, toggle etc.

Other objects of the invention are to provide a concealed hingeparticularly for automobile doors which will be comparatively simple inconstruction, strong, durable, highly efficient and reliable in use,compact and which may be manufactured and installed at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a view in front elevation, showing a pair of hingesconstructed in accordance with this invention installed with a doormounted thereon, said door being shown in open position.

Figure 2 is a horizontal sectional view through an upper portion of theinvention, showing the door in closed position.

Figure 3 is a horizontal sectional view substantially similar to Figure2 but showing the door in open position.

Figure 4 is a view in vertical section, taken substantially on the line44 of Figure 2.

Figure 5 is a view in front elevation of the invention with the door inopen position and the panel removed therefrom, the stop bolts beingshown in cross section.

Figure 6 is a view in horizontal section, taken substantially on theline 66 of Figure 4 with the pin omitted.

Figure '7 is a detail view in perspective of the toggle.

Figure 8 is a detail view in perspective of the door supporting member.

Figure 9 is a detail view in perspective of the pin which connects thetoggle to the door supporting member.

Figure 10 is a view in horizontal section through the upper portion of aslightly modified form of the invention, showing the door in closedposition.

Figure 11 is a horizontal sectional View through the modificationsubstantially similar to Figure 10 but with the door in open position.

Referring now to the drawings in detail, it will be seen that thereference numeral I designates an automobile body and 2 is a door of thevehicle. The opening 3 in the body I which accommodates the door 2 hasformed therein a chamber 4 in which vertically spaced, horizontal plates5 are rigidly secured in any suitable manner.

It will be observed that the plates 5 are spaced from the top and bottomof the chamber 4 and said plates have formed therein vertically alignedcam slots 6 of substantially the shape seen in Figure 6 of the drawings.

Extending into the vehicle door 2 from the hinged end thereof is anelongated pocket 1 which is adapted to slidably receive the free endportion of a supporting member 8. The supporting member 8 comprisesduplicate angular legs 9 having their free ends hingedly secured to theouter side wall of the chamber 4 in the body I, as at H]. The legs 9 aredisposed one above the other in a manner to provide a space Htherebetween. Longitudinal slots [2 are provided in the member 8, saidslots accommodating stop bolts or the like i3 which are mounted in thedoor 2. Vertically aligned elongated guides l4 are provided on thepivoted end of the member 8.

The reference numeral l5 designates generally a toggle which is operablein the space I I between the angular legs 9 of the supporting member 8.The toggle I5 includes hingedly connected sections "5 and I1, the latterhaving one end also pivotally secured to the outer side wall of thechamber 4 at H). The section l6 of the toggle I5 is hingedly connectedto the adjacent end of the vehicle door 2 through the medium of a platel8 which is recessed in said door and secured thereto. Projecting fromthe section I! of the toggle I5 is an elongated guide l9 which extendsat an angle relative to the guides l4 of the member 8.

The reference numeral designates a connecting pin which is adapted totravel in the cam slots 6 of the plates 5, said pin passing through theguides 14 and I9 of the member 8 and the toggle I5, respectively. It maybe well to here state that the pin 20 connects the toggle [5 to the doorsupporting member 8 for actuation thereby. The pin 20 is provided with ahead 2! on its upper end which rests on the upper plate 5.

Briefly, the operation of my improved hinge is substantially asf0llows:-

When the vehicle door 2 starts to move toward open position, the member8 on which said door is slidably mounted, swings in a horizontal planeon its pivot ll]. This causes the pin 20 to travel in the cam slots 6 ofthe plates 5 and in the guides M of the member 8 in a manner which isthought to be obvious. Movement of the pin 20 in this manner actuatesthe toggle id for causing the door 2 to slide outwardly on the support 8as said door opens to .allow for the usual curve or bulge of the vehiclebody and door, as shown in Figure 10f the drawings. During thisoperation the pin 25 also moves longituo- I dinally in the guide IQ ofthe toggle 15. In the arrangement shown in Figure l of the drawings, twoof the hinges constituting the present invention are provided for thevehicle door. Of

course, when the door is swung to closed position the above describedoperation of the elements 8,

I5, 20, etc., is reversed.

In the modification shown in Figures 10 and 11 of the drawings, thetoggle l5 comprises a section 22 which is pivotally secured to the outerside wall of the chamber 4 in the body I. The section 22 includes anangular intermediate portion 23 having mounted thereon in opposed relation thereto a complemental angular bar 24. The bar 24 and the portion23 of the toggle section 22 provide, in conjunction with each other, aguide on said toggle in which the pin 20 is operable. The operation ofthe modification shown in Figures 10 .and 11 is similar to thathereinbefore described for the embodiment shown in Figures 1 to 9,inclusive, of the drawings.

It is believed that the many advantages of a hinge constructed inaccordance with the present invention will be readily understood andalthough preferred embodiments of the device are as illustrated anddescribed, it is to be understood that further modifications and changesin the details of construction may be resorted to which will fall withinthe scope of the invention as claimed.
